Time issue

Hello ya'll,

So I have a 2009 Chronomat Evolution and I was playing with the chronograph and I thought that I would set it to the second hand on my MacBook just to see how accurate the times are. A day later I noticed that the time was about 10 seconds off. Now, about a week later the time is about a minute off!

Then, (this might sound dumb) I figured that I would give it another shot... I went to some website to find the "Exact" EST time and programed my chronograph to that.... to make a short story shorter SAME THING HAPPENED! wtf.....

Is my watch off? I hope not, it is practically brand new and has never fell or anything that could possibly mess up the movement inside!

Help please, opinions would be great!

Watcha,

Does your Macbook (I have the black) sinch with an atom clock?

And (sorry to ask) do you keep your B fully charged?

All of my Bs keep pretty much spot on since 06 on atomic checks (worth a atom)

I had a similar issue with my Chronomat Evolution which was resolved by returning it to the AD see link

There's likely nothing wrong.

If it's brand new then it will take a few weeks to settle, then it should be within COSC specs of -4 / +6 seconds per day.

I would check the watch against an atomic clock instead of the Mac (or PC in my case) - I just don't trust my laptop's timekeeping.

Thank all!

I think I will try NOT running the chronograph however, how would the battery drain? I wear it all the time! :roll:

By wearing it all the time it will keep it wound up. Chronomat Evolution is an automatic so no worry about a battery.

Mainspring will still partially run down overnight, even if worn.

So, to clear things up.... even though the watch is obviously an automatic one and I wear it all the time, running the Chronograph will slow the actual time of the watch down? Is that correct?

I checked it today again after programming it to an atomic clock on the internet and its loses about 5-6 seconds daily.

I am basically just looking for an answer here to why this is happening lol I know for a fact that the watch has never fell or anything so it can not be the watch itself, unless something happened during the manufacturing process.

Chrono doesn't slow the watch down, it will reduce the power reserve.

The watch is cosc certified to -4 / +6 seconds per day, so it''s just outside of those specs.

Take the watch off at night and leave it lying on it's back for a couple of nights and see what happens to the accuracy.

Should I let it completely die off or not though? I do do that every night, it losing about 5-6 seconds per day!

Sorry, didn't realise that it came off every night.

If it's losing 5-6 seconds on it's back then get it regulated - they'll time it exactly and get it adjusted for you. Just make sure that you wear it for a while before the regulation to give it a full mainspring - as it's a daily wearer that will be the most accurate.
